Microsoft makes Copilot Voice and Think Deeper unlimited for free

There is nothing more frustrating than having an AI cut you off mid-thought with a polite message saying you have hit your daily limit.

Microsoft just solved that headache for everyone. On February 25, 2025, the company announced that it is dropping all usage caps on Copilot's Voice mode and its Think Deeper reasoning feature for free users.

Mustafa Suleyman, head of Microsoft AI, put it bluntly on social media: people loved the features, kept slamming into the caps, so Microsoft simply decided to get rid of the limits altogether.

Unlimited o1 reasoning and open-ended voice

Microsoft actually slipped OpenAI's o1 model into the free tier last month, but it kept the guardrails on with tight query quotas. Now, those boundaries are gone.

That means you can spin up Think Deeper to tackle multi-step logic problems, audit hairy blocks of code, or brainstorm technical projects across long, uninterrupted threads without worrying about running out of turns.

The same goes for Voice. Instead of a quick demo that cuts off after a few minutes, you can now use it like an open-ended phone call, throwing questions back and forth in real time.

There are still a few real-world catches. Microsoft noted that free users might experience latency or brief interruptions during peak traffic hours. The service also remains blocked for users coming from Russian IP addresses under company compliance rules.

Meanwhile, the $20 per month Copilot Pro plan is not going anywhere. Paying subscribers keep their fast lane during traffic spikes, get first dibs on experimental features, and retain full Copilot integration across Microsoft 365 apps like Word, Excel, and PowerPoint.

Why it matters

We think this is one of Microsoft's sharpest distribution plays in months.

For everyday users, the practical value is immediate. OpenAI's o1 reasoning power has largely been locked behind a $20 paywall or strangled by stingy trial limits. Opening it up without query caps means students, casual builders, and curious pros can lean on advanced reasoning for complex research without watching the clock.

For the broader AI landscape, this puts real heat on Google and OpenAI. Two years after first putting Copilot into Bing, Microsoft is using its massive Azure muscle to commoditize heavy compute. When the most expensive reasoning models become free utilities on Windows, holding back free tiers behind strict query walls looks far less appealing to users.

The obvious question is how well the infrastructure will hold up. Deep reasoning and real-time audio chew through serious GPU cycles. If free sessions start lagging heavily during working hours, Microsoft might test the patience of the very crowd it is trying to win over. But as a strategy to pull people into the ecosystem and tempt power users into Pro, it is a bet worth watching.
